Nofollow / $\text{rel=”nofollow”}$

The rel=”nofollow” attribute value is a directive used within a hyperlink to suggest that search engines should not crawl that specific link and, crucially, should not pass link equity (or authority) through it to the destination page. A key implication of using nofollow is to disavow association with potential bad practices, suchastically links that have been paid for or are placed in untrustworthy contexts (like spam comments). Note: Google now generally treats nofollow as a hint rather than a strict directive.
